This is a discussion on boost gauge? within the Interior Mods forums, part of the Tech & Modifying & General Repairs category; iv seen really expensive boost gauges and really cheap ones but i dont know which to get. whats a good ...

I my self prefer a mechanical boost gauge, over a electronical one because mechanical runs off air preasure in the system and it really shows the flucuation between vac pres and psi. But thats just me.

I have a mech Autometer carbon series boost and an electric oil pres. I bought them because my car has the optional carbon trim pieces.

No way in hell I would get Defi, there way to expensive, but they are mad "jdm" though

Autometer too bright

I just installed an Autometer Boost gauge from Advance Auto Supply (or maybe it was Autozone?). It works great, seems to be accurate, responds instantly, cost only $40, and was easy to install. The light (the newer LED version), however, is WAY too bright at any setting (it is hooked into the dash light dimmer). Five hours on the interstate at night would render me blind, so I inserted an 820 ohm resistor in the supply line (the line before the little converter/power supply included with the gauge), which tamed the boost gauge lighting just the right amount---your preference may vary of course. Someday I'll get the bug to change the LED (if that's what it is) to a redish one to better match the rest.

Nine Autometer LED gauges---OMG!

You must have tinted windows to keep from lighting up the street at night. Have you investigated what would be involved in changing the LED's to a different color? I didn't see any obvious way to open the boost gauge---looked like it was crimped together, and a PITA to open without breaking something.
